Any chance of a breakout board for the ADV202?
Geeze that would be a serious pain to check for soldering.
I’ve looked at the chip before, but what are you planning on using to capture all that data? You’re talking custom hardware on a higher end CPU (ARM 300 MHz, ala Gumstix, and probably faster required), plus you need a place to store or send that data from that can keep up with those data rates. Which is pretty much a computer hard drive. I really see this chip as just beeing too complex for a breakout board.
You could pair it with an FPGA, but you’re back to a custom PCB anyway unless it’s compatible with the high end Digilent boards. And if you know gate design well enough to put it on an FPGA, you might as well implement the codec yourself

It could be used in wireless video, usb web camera, portable cam recorder, and tons of other apps I think pretty much any 16/32 bit cpu could comunicate with it and as far as the data rate by varring the compression I think you could get a pretty managable datastream 128kbps or so. A good mpeg-4 encoder would be a nice chip to have setting around also i know that mpeg-4 supports anywhere form 8kbps to 5mbps.
Ok, that may work. I’d be concerned with so many pins toggling so fast to get data into/out of the design via an uncompressed interface. Now, I could see an option that has a compressed output via 0.1" headers to your favorite MCU, while the input is a high density surface mount FPC board to board header, reducing size and reducing noise. Then the user could select an analog encoding board, or even a board that jumpered in a control interface for the cell phone video cam. The support boards would probably need their own microcontrollers to provide control signals to make the two chips work together, but it’s a start. Just have to be careful when swapping boards Mind you, you probably wouldn’t much, but still I’ve damaged a few of those connectors for the cell cam already…
It’s not the size really (although that would be one good sized breakout board), but the noise and RF I’m more worried about from an engineering standpoint.
Hello:
I am working on a Breakout board for the ADV202 right now. Its actually completed, I am just trying to get the path to lowest cost manufacture. I am kind of hung up on how many to initially build. It will be somewhat expensive as the chip and BGA assembly are expensive.
Details:
ADV202 144BGA (150MHz) Populated
Decoupling Caps on All Power Lines.
Overall package is a 132 pin Pin Grid Array on .100" spacing. (14x14 grid with 3 rows, center empty.) Kind looks like a small x386 chip
Dimensions 1.4"x1.4"
As soon as I get these off to the FAB, I’ll post again. In the mean time, if there any suggestions please let me know.
I’m not sure if this would help you, but Schmartboard makes breakout boards for BGA’s :

The boards are about 2" x 2". I’ve never used one, but I’d be interested in hearing how it goes. Their option may be less expensive then getting a board fabricated. (I’d also be interested in hearing where you got a BGA board fabricated, and how much it cost, if you go that route too ).
thanks

It runs on Xilinx Microblaze soft cpu. Do you have to pay for that? I must be missing sometihng…
